Granuloma annulare is a long-term ( chronic ) skin disease consisting of a rash with reddish bumps arranged in a circle or ring. It appears most often over knuckles and other joints or in places that are subject to frequent, mild injury such as the back of the hands or top of the feet. GA may be localized, generalized, perforating, or subcutaneous. Lesions of the first 3 presentations have similar appearances, but each one follows a distinctive clinical course. Granuloma annulare is a benign inflammatory dermatosis characterized clinically by dermal papules and annular plaques. Its precise cause is unknown. Patients usually notice a ring of small, firm bumps (papules) over the backs of the forearms, hands or feet. Occasionally, multiple rings may be found. In a few people, clusters of granuloma annulare bumps erupt when the skin is exposed to the sun. Granuloma annulare may be pearly white, skin-colored, red, or purple. Fibromyalgia causes It is most often an isolated area, but may appear as several "bumps" spread all over the body. It is often seen on the tops of the hands and feet, elbows, and knees. Granuloma annulare may cause no symptoms, but affected areas are often tender when knocked.
Granuloma annulare is a chronic degenerative skin disorder. GA is occasionally quite widespread (generalized GA) and this may be an entirely different condition. In these cases the bumps are often smaller and the rings harder to see. PG is a disorder of angiogenesis whose underlying etiology remains unknown. Subcutaneous GA most often manifests as a large, asymptomatic soft tissue mass. Although nodules are usually stable for months, they may rapidly enlarge over the course of weeks. A predilection exists for the head and neck, although lesions may appear on any part of the body. Because granuloma annulare is usually asymptomatic, treatment may not be necessary except for cosmetic reasons. Most lesions of granuloma annulare disappear with no treatment within two years. Women are affected twice as often as men. The localised variety is usually found under 30 years old. The generalised type has peaks at under 10 and 30 to 60 years. People with large affected areas often benefit from treatment that combines phototherapy (exposure to ultraviolet light) with the use of psoralens (drugs that make the skin more sensitive to the effects of ultraviolet light).
Light therapy: In severe cases of generalized granuloma annulare, your doctor may recommend a special kind of ultraviolet light therapy called psoralen plus ultraviolet A (PUVA).
In cryotherapy, your doctor applies liquid nitrogen to the affected area with a cotton-tipped applicator or a small instrument designed for applying extreme cold (a spray device or a cryoprobe) .
